Synthesis and biological activity of a bivalent nucleotide inhibitor of ribonucleotide reductase
摘要:
A novel nucleotide inhibitor (ADP-S-HBES-S-dGTP) of mouse ribonucleotide reductase was designed to span the active site and the allosteric specificity site of the enzyme. The inhibitor contains ADP and dGTP moieties which are linked by 1,6-hexane-(bis-ethylenesulfone), and has a K-i value of 12 muM. (C) 2000 Elsevier Science Ltd. All rights reserved.

Tritium-labeled nucleoside 5′-triphosphates (NTPs) nucleoside 5′-diphosphates (NDPs) containing the tritium label in positions 8 (in the purine nucleus) and 5 (in the pyrimidine nucleus) have been obtained by the dehalogenation of the corresponding bromine derivatives with gaseous tritium. The dehalogenation of the Br-NTPs and Br-NDPs was carried out at atmospheric pressure in an aqueous alkaline medium
